ROBERT FARIES, OF DECATUR, ILLINOIS.

MACHINE FOR FORMING lNTERLOCKlNG-EYES.

SPECIFICATION forming part of Letters Patent No. 321,013, dated June 30, 1885.

Application filed September 10, 1894. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT FARIES, aresi dent of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Machines for Forming Interlocking-Eyes, of which the following is a specification.

My invention relates to the construction and arrangement of mechanisms by means of which interlockingconnections are formed between sections of wire; and it consists in the various parts and combinations set forth in the appended claims.

In the drawings accompanying and forming a part of this specification, Figure 1 is afront elevation of my machine. Fig. 2 is a plan of the platform formed on the upper end of the upper portion of my interlocking device. Fig. 3 is a longitudinal diametrical section of a shaft and pulley used to secure the interlock by coiling the free ends of the wire around the body of the same. Fig. 4.- is a longitudinal diametrical section of the upper portion of my interlocking device. Fig. 5 is a perspect-ive view of the principal parts of the Figs. 6, 7, and 8 serve to illustrate various steps in the operation of the interlocking device. Fig. 9 shows the connection of the wire half formed, and Fig. 10 represents the same completed.

As indicated in Fig. 1, my invention may be classed in three divisions: First, the upper portion of theinterlocking device; second, the lower portion of the same; and third, the mechanism employed to coil the free ends of the wire around the body of the same after the interlock has been effected.

The reference-letters refer to various parts, as follows:

a is a platform rigid on vertical shaft 1'.

b (see Fig. 2) is asegmentalguide-ridge elevated from the upper surface of platform a.

c is a spur projecting upward and outward from the circumference of the platform.

. d is an elevation lying in an approximately radial position on the platform, and e is a vertical inclination on the same.

ff is a bent lever, provided with a fulcrum in frame 9.

g is a rod that extends from lever f through shaft r. (See Fig. 4.)

h h are friction-pulleys rigidly attached to cylindrical shaft'h. (See Fig. 8.) v i is a vertical tubular standard rigidly attached to the frame of the machine.

k k, in Fig. 1, are braces that operate in a manner to be hereinafter set forth.

H are rotating arms rigidly attached to shafts h of wheels 71.

m m, as indicated by dotted lines in Fig. 1, are bent levers, connected with an operatingbar by means of rods m'm. A spring, m", also connects with the operating-bar above mentioned, holding said bar and levers in the position indicated.

a is a beveled friction pulley, supported in upright 1 and operated by belt-pulley 0.. (See Fig. 1.)

p, in Fig. 3, is a tubular shaft havinga limited amount of free motion longitudinally in shaft h.

p is a longitudinal groove in shaftp, and

p is a short groove lengthwise of the same.

q represents a frictional spring in groove 1).

r is theshaft to which platform a is rigidly attached, and 1" is a support for said shaft.

sis a shaft to which frame g is rigidly attached.

tis a shaft having a limited amount of rotary motion in standard 2'.

a is a lever used to partially rotate shaft t.

10 c are sliding plates on which pulleys h h have their bearings, and w w are guides for the same.

00 represents upward proiections on shaftt.

y shows downward projections from shaft 8.

z indicates the Wire. The spring 4 in Fig. 4 tends to hold the wire firmly between the ends of shafts s and it while the eyes are being formed.

In operation the wire is passed through tubular shaft 10 and the ends placed in the posipenetrate theopening in shaft tand to slightly deflect the wire. A further step in the operation consists in rotating lever f to the left until its bent end f comes in contact with spur c, as shown in Fig. 8.

Fig. 7 shows the above-mentioned result one-half effected, and the result is as follows: As the rotation proceeds the projections on shaft 8 engagethe ends of the wire and bend thesame around the lower end of rod while the block on frame 9 ascends incline e and raises the said ends clear of the body of the wire, thus overcoming all impediments to the operation. When the lever f comes in contact with spur c, as shown in Fig. 8, the interlock will be formed, as indicated in Fig. 9. To complete the operation, shaft 8 is adjusted as shown in Fig. 6, and shaft t as shown in Fig. 5, after which the ends of coiling-shafts 2o 1) are made to engage the free ends of the wire and motion is imparted to pulleys h h in opposite direction by contact with rotating bevelpulley n, thereby effecting the coils, as indicated in Fig. 10. It is evident that the coiling-shafts must recede from each other while forming the coils, and this is provided for in recess 19", which permits said shafts to move longitudinally to a limited extent in cylinder h. Friction-springs q are relied on to offer a sufficient resistance to the receding motion of the coiling-shafts, and the disadjustment following the said receding motion is corrected after each operation by braces k k offering resistance to the ends of the shafts p and returning the same to their places. To enable the wire to pass out of the machine after the interlock has been completed, a lateral opening is formed longitudinally in one of the coilingshafts, and a cavity of sufficient size to permit the joint to pass, formed through cylinder h. See Fig. 5, where such an arrangement is indicated.) To cause the coiling-shafts to stop always in the same position, levers m m are made to engage arms Z Z after each operation. (See Fig. 5.) NVhen the lever f is in the position indicated in Fig. 5, its bent extremity rests be tween elevations b and d, supporting-frame g and rod and a downward motion of said lever on a vertical line will produce the position shown in Fig. 6. The spring m, by operating through rods mm and bent levers m m, causes friction-pulleys h h to recede from each other after the completion of each coiling operation.

When the arms I move horizontally toward each other they become detached from the slotted ends of the bent levers m m and permit friction-pulleys h h to rotate freely when they come in contact with pulley n, and when the said pulleys h h recede from each other their momentum is arrested by the ends of arms Z again coming in contact with the ends of the bent levers.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A. vertical tubular limitedly rotating shaft, t, provided with upward projections 04:, a vertical tubular rotating shaft, 8, provided with downward projections y, a rod, 9, adapted to operate vertically in shaft 8 and reciprocatingly penetrate shaft t, and suitable means for operating rod 9' and rotating shaft 8, all adapted to operate in combination for the purpose of effecting an interlock between two ends of wire, substantially as set forth.

2. The combination, in a machine for forming interlocking-connections between two ends of wire, of a vertical tubular limitedly-rotatin'g shaft, t, vertical tubular rotating shaft 8, rod 9, frame 9, block 6, lever ff, and platform a, provided with spur c and incline e, as and for the purpose set forth.

3. The combination of shafts t 8, rod 9, frame 9, levers ff, and platform a, provided with spur 0, incline c, segmental elevation b, and radial elevation d, as and for the purpose set forth.

4. The combination of tubular rotating shaft 8, tubular shaft t, having a limited amount of rotary motion, standard t, and lever u, as and for the purpose set forth.

5. The combination of cylindrical shafts 71/, provided with rotating pulleys, tubular shaft p,provided with slots pp, and friction-spring q, located in slot 1), all constructed and arranged to co-operate for the purpose of coiling an end of wire around the body of the same, as set forth.
